Research contextWhat must be decided, and on which evidence?
Additive manufacturing can enable new geometries, but the business case depends on material properties, build repeatability, post-processing and part acceptance criteria.
Powder bed fusion, directed energy deposition, material extrusion and other processes are not interchangeable. Build volume, feature limits, surface finish and validation requirements differ.
The research is designed for Additive manufacturing firms; industrial designers; manufacturing investors. A useful first question is whether the available records are suitable for a procurement decision, a financing discussion, an investment thesis, a partnership negotiation or a research roadmap. The quality of those records varies: journal articles, patents, supplier disclosures and field test logs are not interchangeable. Each material finding should be tied to its date, test boundary, source and remaining uncertainty.
There are three different levels of statement to keep apart: a technology may be technically feasible; a specific supplier may have documented evidence of implementation; and a planned project may still be economically or institutionally unsuitable. Research supports a more disciplined comparison of those levels without converting a plausible hypothesis into a guarantee.
